However, extensive skeletal isomerization crucial for high-octane gasoline production remains a fundamental and unresolved limitation. Herein, we introduce a self-confined adsorption-configuration strategy that enables isomerization during polyolefin hydrogenolysis. By enforcing single-point adsorption on isolated Ir sites, \u03b2-scission intermediates gain the geometric freedom necessary for carbocation rearrangements, ultimately enabling the direct production of high-octane gasoline under solar-thermal conditions. In addition to promoting internal C\u2013C bond rearrangement, the confined adsorption mode suppresses terminal cracking pathways. The Ir SA\/WO3 catalyst achieves 92% conversion of polyolefin waste to liquid hydrocarbons while nearly eliminating methane production. Overall, this work advances a practical route for upcycling waste plastics into valuable energy products, contributing to a more closed-loop and carbon-efficient anthropogenic carbon cycle.<\/jats:p>","DOI":"10.1021\/jacs.6c07894","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T13:17:23Z","timestamp":1785849443000},"page":"33433-33442","source":"Crossref","is-referenced-by-count":0,"title":["Confined
